This version of opam requires an update to the layout of /home/opam/.opam from version 2.0 to version 2.2, which can't be reverted.
You may want to back it up before going further.

lwt_ppx.2.0.1 is not installed. Install it? [Y/n] y
  * Incompatible packages:
    - (invariant) -> ocaml-base-compiler >= 5.4.0 -> ocaml-compiler = 5.4.0 -> base-effects
    - lwt_ppx = 2.0.1 -> ocaml-migrate-parsetree >= 1.5.0
    You can temporarily relax the switch invariant with `--update-invariant'
